This invention relates to door operating devices embodying among other characteristics, means for actuating the same at remote points therefrom.

Another object of the invention comprehends means adapted to automatically reverse the direction of the doors.

A further object of the invention contemplates auxiliary switch members adapted to manually control the actuating means whereby the disposition of the doors may be regulated.

More specifically stated the operating means is connected with a cut off mechanism adapted to render the same inactive when the doors are swung to occupy desired positions.

With the above and other objects in view, the invention further consists of the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

Referring to the drawings in detail, wherein like characters of reference denote corresponding parts, the reference character 10 indicates a plate member carried by and suspended from or otherwise supported by bracket members 11 adjacent the ends thereof which are in turn connected with the ceiling of a garage or other storage place requiring entrance closures. An electric motor 12 being carried upon one end and preferably upon the upper side of the plate member 10 .and adapted to operate a threaded shaft 13 in reverse directions, the purpose of which will be resently apparent. Said shaft being journaled at its opposite end within a bearing member 14 carried upon one end of the plate member 10 in op osed relation to that of the motor 12. ngle plates 15, adapted for connection with the side edges of the plate member 10, are adapted to define a channeled groove 16 adapted to accommodate a shoe or foot 17 slidably mounted upon the upper side of the plate member 10. A tongue 18, upstanding from the shoe 17, is bifurcated, as indicated at 19, to support a connecting block 20, provided with forward- 1y projecting apertured cars 21, adapted to accommodate the innermost ends of rod members 22, having connection with bracket members 23, carried upon the inner sides of companion doors 24. The threaded shaft 13 is extended through the side walls upon the opposite sides of the bifurcation 19 in the tongue 18 of the shoe 17 and within the block 20 disposed in said bifurcation 19, whereby the threaded shaft not only provides the necessary connection between the tongue 18 and block 20 but which also causes simultaneous sliding movement of the same.

Brackets 25, slidably mounted upon the angle plates 15, are provided with openings 26 adjacent the extremities thereof and adapted to accommodate a shaft 27. The latter mentioned brackets being provided with channeled portions 28 adapted to effectively engage the angle plates and the underside of the plate member 10 in the manner as best illustrated in Figure 4 of the drawings. Bearing members 29, depending from the undersides and adjacent the ends of the plate member 10, are provided with spring pressed balls 30, adapted for selective reception within pockets 31, provided adjacent the ends of the rod 27. Compression springs 32 being arranged between the adjacent sides of the brackets 25 and the bearings 29. Set screws 33, extended within the extremities of the brackets 25 and within the openings 26 thereof, are adapted to rigidly engage the shaft 27. The uppermost ends of the bracket member 25 are located in the path of movement of the tongue 18 for the shoe 17.

The end of the shaft 27, adjacent the motor 12, is curved and olfset as indicated at 34 and which terminates to provide an elongated plate 35 having a diagonally disposed slotted portion 36 adapted to accommodate a reverse lever 37 for the motor 12.

From the foregoing description and accompanying drawings, it is readily apparent that the motor 12, when set in motion, will rotate the threaded shaft 13 and cause the shoe 17 to slide within the channeled portion 16 defined by the relative arrangement of the plate member 10 and the angle plates 15. The tongue 18 of the shoe 17, upon engagement with either of the brackets 25, will shift the rod 27 in a corresponding direction, and the latter, due to its connection with the reverse lever 37, will cause the motor 12 to rotate in an opposite direction. Such action will continue until the circuit connected with the motor 12 is opened. Obviously, during such reverse operations, the doors 24 will be opened and closed.

It is my intention to render the apparatus automatic in operation and to effect such operation, I provide a compartment 38, preferably sunken within the drive-Way leading or approaching the doors 24. A treadle 39, hingedly mounted, as indicated at 40, within the top of the compartment 38, is supported beneath its opposite side by compression springs 41 within the compartment. A Shaft 42, rotatably mounted within the compartment 38, carries a ratchet gear 43 adapted for engagement with a pawl 44 to restrict movement in one direction, is also adapted for engagement with a pawl 45 operable by the treadle 39 through the instrumentality of a connecting rod 46 carried upon the underside .thereof. A dielectric disk 47, carried upon the shaft member 42 and adapted for simultaneous operation therewith, is provided with multiple contacts 48 upon diametrically op posite sides thereof adapted for contacting engagement with spring contacts 49 and 50, arranged upon the opposed side Walls of the compartment 38.

From the diagrammatic plan view in Figure 2 of the drawings, wherein I have illustrated the wiring circuit adapted to establish communication between the treadle operating means and operating means per se. It is noted that the switch member 47, when shifted to occupy the position as illustrated in Figure 2 of the drawings to close the circuit between conducting wires 51 and 52; the conducting wire 51 being included in circuit with switches 53 and 54, the latter being connected in circuit with a source of current, as indicated at 55. The opposite terminal of the source of current energizes a magnet 56, the other pole of the magnet having connection with the remaining conducting wire 52. A pivoted switch member 57, when magnetized by the magnet 56, causes contacting engagement of the free end thereof with contacts 58 and 59 having connection with conducting wires 60 and 61 respectively. The Wire 60 establishes communication between the contact 58 and source of current 55 through a lead wire 62 to the motor 12. The conducting wire 61 is also connected with the motor 12 whereby the motor circuit is completed.

A vehicle when approaching the doors .24 encounters the treadle 39 with one of the front wheels therefor. Depression of the treadle 39 will cause the switch 47 to occupy the position as illustrated in Figure 2 of the drawings and the aforementioned circuit will be completed. The doors 24 will then open, due to their connection with the operating means. The rear corresponding wheel of the vehicle when depressing the treadle 39 will shift the switch member 47 to occupy the dotted line position, as illustrated in Figure 2 of the drawings, but the motor circuit will not be open, due to the presence of a dog 63 which engages one end of the switch member 57 to sustain the latter in the position shown;

The doors 24 when swung to their utmost open positions will actuate the reverse lever 37 for the motor 12 incident to the connection of the plate member 25 and shaft 27 therewith. The doors will then begin to close and the vehicle by this time is parked within the garage. When the doors have been completely closed and the reverse operating means for the motor 12 partially shifted in an opposite direction, the reverse lever 37 will be brought into contacting engagement with a lever 64 pivotally mounted, as indicated at 65, and which will bridge the space between contacts 66 and 67. The contact 66 being connected in circuit with the source of current 55 through a lead wire 68. The contact 67 being connected with a relay 69 through a contact wire 70. The relay 69 will thus be energized and the dog 63 attracted thereby, whereby the switch 57 will be released and the motor circuit opened, and whereby the motor will cease to function and the doors 12 will be disposed in closed positions.

When the reverse lever 37 is shifted in an (iipposite direction from that as illustrated in igure 2 of the drawings to actuate the lever 64, it is to be noted that the motor circuit will not be open, due to the fact that the lever 64 is provided with a hinge connection 71 at an appropriate point in the length thereof and which will prevent contacting engagement of the contacts 66 and 67 therewith.

Either of the switches 53 or 54 may be arranged within the house and the other within the garage, whereby the opening and closing actions of the doors may be operated independently of the treadle.

It is further to be noted that either of the switches 53 or 54, when opened, will prevent unauthorized ingress and egress to and from the garage, whereby the opening of the cirm cuit simulates a lock.

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.
